Homonyms - 2 words that sound alike but have different meanings. For example, "read", as in "I read the article, yesterday", and "red", as in the color red. "Hair", as in what grows out of your head, and "heir", as in the someone who will inherit (The eldest prince is heir to the throne). It may be helpful to remember that "homo", from the original Greek, means "same". So homonyms have the same sounds.
